The magician shows his audience an old magic trick with an oversized domino. First, the two-sided domino has one spot on it. The other side has four. But when the magician turns the domino over again, it is shown to have three spots on one side and six on the other.

The magician then explains the trick. But the explanation proves more puzzling than the trick first demonstrated. Spots on the domino multiply unexpectedly, proving the magicians explanation useless. In the end, the domino is full of new spots - eight on one side and three on the other.
